Spend Analysis: the 3 maturity levels
Objective: Understand the 3 levels of spend analysis and know how to apply them to turn raw data into actionable insights.
Spend Analysis is the Category Manager's first tool. It is the foundation of any procurement strategy: without a clear understanding of your spend, it is impossible to prioritise, negotiate effectively or build a solid category strategy.
Level 1 - Descriptive analysis: What happened?
Descriptive analysis answers the fundamental questions about past spend. It is the photograph of the current situation.
- How much do we spend in total? Per category? Per supplier?
- How is spend distributed across business units, sites, countries?
- What is the trend over 3 years?
- What is the direct vs. indirect procurement ratio?
Level 2 - Diagnostic analysis: Why?
Diagnostic analysis goes beyond observation to understand causes and identify anomalies.
- Why did the packaging category increase by 23%?
- Why do 3 business units buy the same product from 3 different suppliers at different prices?
- Why is contract coverage only 45%?
- Why does tail spend account for 35% of supplier count but only 5% of spend?
Level 3 - Predictive analysis: What will happen?
Predictive analysis uses trends and market data to anticipate how spend will evolve.
- If steel prices rise 15%, what is the impact on our metal components category?
- Which contracts expire in the next 12 months and what is the risk of price increases?
- What will our logistics capacity needs be if volume grows 20%?
The 6 dimensions of analysis
Whatever the level of analysis, spend must be examined across 6 complementary dimensions:
| Dimension | Question | Example insight |
|---|---|---|
| By category | Which categories weigh the most? | IT = 22% of total spend, but 45% of suppliers |
| By supplier | What is the concentration? | Top 10 suppliers = 62% of spend |
| By BU / department | Who spends what? | Marketing buys EUR 3M of IT services without going through procurement |
| By geography | Where do we spend? | The Lyon site pays 18% more than Paris for the same cleaning service |
| Over time | How does spend evolve? | Energy: +34% in 2 years, an unsustainable trend |
| By purchase type | What is the direct/indirect mix? | Indirect = 40% of spend but only 15% of buyer time |
💡 Key takeaway: A mature Spend Analysis covers all 3 levels (descriptive, diagnostic, predictive) and systematically crosses the 6 dimensions. Most organisations remain stuck at the descriptive level: they know how much they spend but not why, nor how to optimise.
